A Family of Even-Point Ternary Approximating Schemes

Abstract EN

We presented a general formula to generate the family of even-point ternary approximating subdivision schemes with a shape parameter for describing curves.

Some sufficient conditions for C0 to C7 continuity and approximation order for certain ranges of parameter are discussed.

The proposed even-point ternary schemes compare remarkably with existing even-point ternary schemes because they are able to generate limit functions with higher smoothness and approximation order.

In addition, we measured curvature and torsion that assist the quality of subdivided curves.
